But seriously... I think you should take Brick up on his non-too subtle offer.
Sure, you might have to go to the clinic next Saturday, but don't let a thing like infection stand between you and the best 2 minutes of your life
But, seriously..... seriously : I think Shrek was right in what he was trying to get across.
Often women in particular get this ideal 'weight' in their head. Or perhaps once, they were at that weight. There are a few factors to consider as to why you're now struggling to shift the last few kilos.
TBH at your height, you're taller than me, and I would not call 64kgs overweight for your height.
Perhaps you are stressing yourself out more than anything, trying to achieve this 'goal weight'.
You may find that if you're trying to use the same training and techniques that got you down to your 'ideal' weight, it is time for a change.
Try some periodization. Different exercise. Mixing up your diet.
You would have worked out your macros etc?
Clen is not something to be toyed with and peptides would not be $$ well spent in your case imo.
Your bf should not be condoning its use lightly either, if he is.
I'm a coffee addict too, but perhaps you could try subbing it with some green tea for a bit.
